Thanks to my lovely wife, I got some 9mm reloading stuff for Christmas and just found some time to setup my Dillon 9mm dies, toolhead assembly and configure them to reload 9mm.
I did have a question to anyone who’s reading this who has experience reloading 9mm, here’s a pic of the finished product, OAL is 1.125 (as suggested by Hodgdon). Why is there a dip (or taper) in the middle of the ammo? Is that normal?
The diameter at the rear of the case is 0.388, the middle is 0.376 and the neck is 0.377-0.378.
Am I doing something wrong?
From various friends and forums, the Coca-Cola bottle / Hourglass shape of the 9mm round is normal, the case isn’t straight walled like a .40S&W or a .45 ACP. The round above though doesn’t have enough crimp. I’ve added more crimp and taken another picture to compare :
The neck is now .375-.376. Looks much better. That said, when I pulled the bullet, the crimp leaves a mark. I’m not sure if this is good or not.
